STR-M6529OFF-LINE SWITCHING REGULATOR – WITH POWER MOSFET OUTPUT
DRAIN1OSC.FAULTLATCHData Sheet28102.1SOURCE2RCOMMONOVER-CURRENTPROTECTIONVINSThe STR-M6529 is specifically designed to meet the requirementfor increased integration and reliability in off-line flyback convertersoperating in the quasi-resonant ringing choke mode. The deviceincorporates the primary control and drive circuit with a discrete ava-lanche-rated high-voltage power MOSFET.
Crucial system parameters such as maximum ON time and OFFtime are fixed during manufacture. Local control circuit decoupling andlayout are optimized within the device.
Cycle-by-cycle current limiting, soft start, under-voltage lock-outwith hysteresis, over-voltage protection, and thermal shutdown protectthe devices during all normal and overload conditions. Over-voltageprotection, thermal shutdown, or an external fault signal are latched.The dual requirements of dielectric isolation and low transient thermalimpedance and steady-state thermal resistance are satisfied in an over-molded single-in-line power package.
Proven in substantial volumes, this device and its fixed-frequencycounterparts represents a significant advance in off-line SMPS reliabilitygrowth and integration.

WARNING — These devices are designed to be operated at lethal voltages and energy levels.Circuit designs that embody these components must conform with applicable safety requirements.Precautions must be taken to prevent accidental contact with power-line potentials.Do not connect grounded test equipment.The use of an isolation transformer is recommended during circuit development and breadboarding.The power MOSFET outputs of these devices are similar to the International Rectifier type IRFPE40. These devicesfeature an excellent combination of fast switching, ruggedized device design, low on-resistance, and cost effectiveness.Recommended mounting hardware torque:
4.34 – 5.79 lbf•ft (6 – 8 kg•cm or 0.588 – 0.784 Nm).
Recommended metal-oxide-filled, alkyl-degenerated oil base, silicone grease:
Dow Corning 340, or equivalent
